Super Ikonta?

I'm pondering perhaps getting more into medium format, but I want to do it relatively cheaply. Zeiss Ikon Ikonta cameras seem to be a good way to do this. I've looked at various models, but the Super Ikontas are the ones that stand out as the best bang for your buck (as long as you aren't looking for mint cosmetics - that can cost you a pretty penny). Does anyone use these? Can you post shots from them? I posted a WTB link on rangefinderforum.com for the non-rangefinder 521/16 model, just as one to test really. Any experience would be appreciated.
